Laptop keeps getting BSOD

Open | BSOD

Hi,

For the past couple of weeks, my laptop has daily been receiving the BSOD message randomly and then restarting.

I've done a full windows system diagnostic check, RAM/Memory check and everything is coming out as good.

The windows log is flagging the crash as Event ID 41: Bug check code 340

I'm not too tech-savvy, so any additional steps/tests you'd recommend for me to diagnose this would be greatly appreciated.

Here are my specs:

Lenovo ThinkpadT480s

Processor: Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz (1.80 GHz)

Installed RAM: 8.00 GB (7.86 GB usable)

Edition Windows 11 Pro

Version 25H2
